The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.

    Abstract: This invention provides an improvement in a no-back device having a ball screw connected to a variable load of reversible polarity (±L) and having a portion penetrating a housing. The device includes a braking mechanism acting between the housing and the ball screw for producing a force that resists movement of the ball screw in the direction of an “aiding” load, but does not substantially resist movement of the ball screw in the direction of an “opposing” load. The improvement broadly includes: a first spring acting between the housing and the braking mechanism for exerting a first preload force (F1) on the braking mechanism for simulating the application of an external load on the ball screw in one of the directions; whereby the apparent operational integrity of the no-back device may be checked when no external load is applied to the ball screw.

    Abstract: A main shaft locking mechanism includes a fixing ring, a main shaft and detents. The main shaft includes an equilateral portion that has an equilateral cross section. A number of the corners of the equilateral portion is equal to that of the detents. The detent has an exterior side and an interior side opposite to the exterior side. The interior side includes two corner protrusions protruded out from two ends thereof and a concave portion defined between the two corner protrusions. The corners of the main shaft are received in the concave portions of the detents. When the main shaft is manually driven to rotate, the corners of the main shaft drive the detents to deviate. Therefore, the exterior sides of the detents interfere against the fixing ring. Then the detents prevent the main shaft from further rotating, thus locking up the main shaft.

  • Patent number: 6722485
    Abstract: A force-limiting rotary lock (20) for a shaft (21) mounted on a housing (22) for rotational and axial movement relative thereto, broadly includes a lug member (28) provided on the shaft, and a pawl (51) mounted on the housing. The pawl is movable relative to the housing between first and second positions. The pawl is operatively arranged to engage the lug when the pawl is in its first position (shown in FIG. 3) to prevent further rotation of the shaft in one angular direction, and to be disengaged from the lug when the pawl is in its second position (shown in FIG. 2) to permit rotation of the shaft in either angular direction. A cam (25) is mounted on the shaft, and a follower (49) is mounted on the housing for selectively moving the pawl between the first and second positions when the shaft is axially displaced from its predetermined position.

  • Publication number: 20030196868
    Abstract: A ratcheting, locking actuator for selectively positioning ergonomic devices is disclosed. The actuator has an overrunning, locking clutch in a housing, a lever, a hanging ratchet and a pulley for anchoring a traction element. The pulley is driven by a gear which is driven by the one of two ratchet pawls in either of two selectable directions. The drive direction is controlled by a lever to which a ratchet post is attached. Engagement and disengagement of the ratchet pawls with the drive gear is controlled by steps on the housing. The actuator is especially useful for controlling traction elements such as bowden cables for ergonomic devices such as lumbar supports.

  • Patent number: 6520583
    Abstract: A compact disc recliner mechanism for reducing chucking includes a drum adapted to be fixed to a quadrant for rotation relative to a plate and three locking members having locking surfaces for locking said quadrant relative said plate. At least one locking member moves relative the quadrant from a first position engaging the drum to a second position disengaging the drum. At least one other locking member is fixed relative the plate and movable from a first position engaging the drum to a second position disengaging the drum. A cam moves the first, second, and third locking members from a first position engaging the drum to a second position disengaging the drum. A recliner assembly for use with a seat having a seat back and a seat base includes the compact disc recliner mechanism according to the invention.

  • Patent number: 6520584
    Abstract: A mechanism (16) adjusts a relative position of a component (14) within the vehicle. The mechanism has a mounting bracket (18). A drive drum (20) is mounted rotatably on the bracket for providing a rotary output to adjust the component (14). An actuation handle (22) is rotatably mounted to the drive drum (20) and rotatable relative to the drive drum (20) from a neutral position. A coil spring (24) surrounds the drive drum (20) in a sliding engagement. A return spring assembly (54) engages the coil spring (24). The handle (22) engages the coil spring (24) and the return spring assembly (54). As the handle (22) is rotated from the neutral position, the coil spring (24) is rotated in a winding sense about the drive drum (20) and against the return spring (54) thereby coupling the handle (22) and the drive drum (20) for rotation.

  • Patent number: 6389917
    Abstract: A safety device for a gear unit driven by a drive mechanism has a rated breaking point. A silent ratchet is also provided, with which a gear part on the power takeoff side that is severed upon a separation of the rated breaking point can be firmly clamped with a silent ratchet. The safety device can be used in devices, driven by an electric motor, for adjusting vehicle seats.

  • Patent number: 6371557
    Abstract: A lever operated rotary drive mechanism, the mechanism including a mounting frame carrying a rotary output member adapted for driving engagement with a rotary drive input, such as a shaft, an operating lever pivotally mounted on the mounting frame for pivotal angular displacement relative to the frame, biasing means for biasing the lever to a rest angular position, the lever being movable within a first angular displacement region located on one side of said rest position and movable within a second angular displacement region located on the opposite side of said rest position and a drive transmission which drivingly connects the lever to the output member to cause rotation of the output member in one rotary direction only on displacement of the lever within said first angular displacement region and to cause rotation of the output member in the opposite rotary direction only on displacement of the lever within said second angular displacement region.

  • Patent number: 6224157
    Abstract: This articulation comprises two coaxial annulus gears with internal sets of teeth (20, 22) of different pitch, one stationary and the other mobile, meshing with at least one planet (S1 to S4) bearing two external sets of teeth (24, 26) capable of mating with the internal sets of teeth (20, 22). The external set of teeth (26) that mates with the mobile internal set of teeth (22) extends over a shorter sector than the other external set of teeth (24), which means that the planet (S1 to S4) can move over a travel in which its two external sets of teeth (24, 26) are in mesh with the two internal sets of teeth (20, 22), between two end-of-travel positions beyond which the stationary internal set of teeth (20) is kept in mesh with the mating external set of teeth (24) while the other external set of teeth (26) is disengaged from the mobile internal set of teeth (22).
